What you need to use firewire cameras:
Firewire camera (of course)
Firewire interface in computer. Make sure it can provide power to the camera if necessary.
NI's IMAQ for 1394 software. This will provide the interface to get the images into LabVIEW.
If you don't want to process the images, that's all you need. If you want the tools for processing, you need the IMAQ Vision Toolkit.
If you want help figuring out the hardware, call Robert Eastlund at Graftek Imaging (800) 441-2118. If you would like help putting together an application, contact me at Ammons Engineering (810) 687-4288.
